ASTM (American Society for Testing and Materials) is working hard on setting & updating test methods so industries can control quality of their products.
Here is the list of usually performed tests (with ASTM testing method) for testing Lube oil:
1. Viscosity @ 40°C, cSt (ASTM D445)
2. Viscosity @ 100°C, cSt (ASTM D445)
3. Viscosity Index (ASTM D2270)
4. Pour Point, °C (ASTM D97)
5. Flash Point, °C (ASTM D92)
6. Density @ 15C, Relative (ASTM D4052)
7. TBN (ASTM D 974,4739)
8. Carbon Residue (ASTM D 189)
Kinematic Viscosity Bath
Kinematic Viscosity Bath AS PER , Viscosity Bath (IP71) for the temperature of 40 degree and 100 degree and also refrigerated upto -35 degree C.:Kinematic viscosity Bath as per ASTM with temp. Range room temp. to 150 deg C along with temp. accuracy +/- 0.1 degree centigrade to accommodate 5 viscometer at a time along with Viscometer holder. It consist illumination facility for better visibility. The stirrer is for better uniformity throughout the chamber. Temp. controlled by thyristor drive temp. indicator cum controller.
